EXTENSIBLE WATER-TOWER 0B.- STAND-PIPE.

My inventionrelates to extensible water towers or stand pipes for extinguishing res, and has for its objects to .provide certain improvements inthe construction of the same,

the accompanylng drawings, 1n which: Flgure 1 1s a side elevation, partly in secbeing shown mounted upon a suitable platform or truck for transporting the same.

2 is a top plan view of the device, the uppermost section of the extensible )art being shown in section. Fig. 3 is an en arged detail plan view of the cam plate' for controlling the extension of the telescopic sectionsof the tower or stand pipe. Fig. 4 is an enlarged detail sectional view of the discharge nozzle.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawings the reference numeral 1 denotes the base or platform upon which' my improved device is mounted, the same being intended-to be mounted on wheeled trucks, not shown, whereby the device may be transported as a water tower. Fixed cenfxed to the under side of the receiving chainber'4 of the device, whereby said chamber may be adjusted at any angle with respect to said platform;

Fitted into the upperside of chamber 4 is the lowermost section 5 of the telescopic tower, said section 5 having an annular flange 6 at its lower end that rests on a similar tained together by a collar 8 bolted to the chamber 4, an interposed packing 9 forming a Water-t' ht joint, and yet permitting section 5 to e rotated on chamber 4. As a ready means of rotating section 5 on chamber 4I have provided on section 5 a toothed ring 10 that is in gear with worm 11 mounted IFixed to the exterior of section 5 at approximately its upper end is a flange 14, and ,1

mounted on said 4flange is a ring 15 free to ro- Extending downward from said ring 15 are two sprocket chains 16 and 17, the same passing around suitable pulleys 18 located. at diagonally opposite corners ofA the platform 1, and passing'thence beneath said platform and in engagement each with a sprocket wheel 19. Said -sprocket wheels are similarly operated', and each has its shaft supported in suitable brackets 20 bolted to the under side of platform 1, ano erating lever 21 for each of said sprocket wlheels being freely mounted on its shaft andcarrying oppositely disposedl plawls 22 adapted to be engaged with Ia rate et wheel 23 fixed to said shaft, whereby said 'sprocket wheels may be rotated in either direction at will, said rotation being communicated to chains 16 and 17 to tilt the section 5 and chamber 4 on the universal bearing in any direction, whereby the tower may be caused to assume a verticalpos'ition under any condition of irregularity of the ground when the truck carrying the device may be stopped.

Nesting within each other are the telescopic sections 24 of the tower,' of which I have shown three, though the number may be varied to suit the height to which the Water is to be carried.. Said sections are main-v tained against disengagement by any lsuit-- able means; for instance, by engaging flanges 25 and 26, and, if desired, said connections may be suitably packed to prevent leakage.

The uppermost of the sections 24 has its upper end 27 bent to a horizontal position and contracted, as shown, and/has pivotally mounted at its discharge end a nozzle 28, normally maintained in its uppermost position by a spring 29, in which position the orihce through said nozzle is out of register with the end of the section, and the iiow of water thereby cut off, asbest seen in Fig. 4. 4To ermit the discharge of water the said nozzle 1s drawn downward by a suitable cord 30 attached to its outer end, and the volume of the discharge ma be regulated by Aangle of said angle gear 34 mounted on a shaft 35, supported in an extension 36 of bracket 31 andf iaving an operating crank 37 fixed` to lts l outer end, a suitable awl 38 being provided to engage with a rate et 39 on said shaft 35 to maintain the parts in any adjusted posi` tion. Said rod 32 passes upwardly through I the flange 14 on section v5, and carries xed.

to its upper end a cam lplate 40, .formed into a series ofirregular cam extensions 41 corresponding 1n number to the number yof eX- 'tensible sections y24 of the tower, said cam ex- 1 tension being adapted, bythe rotation of rod 32 and said'cam plate, to successively overlie the upper edges .of the sections 24 and thus prevent the projection of all or as many of said sections as may be desired. Thus, byf

turning said cam plate to'the position shown lowermost of the sections 24 are free to be projected.. v

yTapped into the side of .chamber-4 is a l'series ofcoupling cocks 42, provided with icut-ofi' valves 43, to which the engine hose 'may be connected to supply-the water.

From the abitve descriptioi f' the operation of my im rovi i construction. vwill be understood as ollows: When the device is transported to the seat of a conlagration, and, owing to the inequalities in the ground where it is brought to rest, the tower is out of a ver tical plane, the same may be readily adjusted to a vertical osition by manipulating chains 16 and 17 t wheels 19. Now, when the hose of one or Amore engines are connected with the cocks 42 and water urnped into the cha1nber'4, the lling of tlle latter and chamber 5 Will,

through thevwater pressure, project the sec tions 24 to their u ward limit of movement,

v the number of sai sections t'o be projected being controlled by the manipulation of cam plate 40 to limit the height of nozzle 28 to the desired degree To direct the up er end 27.

oi' upper section 24 in the desire direction the worm ear 1 1 is manipulated,4 through crank hande 13, whereby section 5 and the sections 24 may be rotated to any position.

of a cam plate, and means for adjusting said cam plate in the path of projection of all or a portion of said sections. l

' 2. In an extensible water tower or stand pipe, the combination with a base section, and a series of .telescopic sections mounted in said base section and adapted to be projected therefrom by the pressure of the water admitted thereto, of a cam plate rotatably mounted on said base` section, and means for 'rotating said cam plate to lie in the path of.

3. In an extensible'water tower or stand pipe, the combination with a base section, and a series of telescopic sections mounted in said base section and adapted to be projected therefrom by the pressure of the water admitted thereto, of a cam plate rotatably mounted on said base section, means for rotating said cam plate to lie in the path of projection of all or a portion of said sections, and means for retaining said cam plate in any adjusted position.
